BlackICE Historical Immersion Mod

In 1 collection by maverick
3 items

We aim to bring Hearts of Iron 4 to an all new level, making your game experience more immersive, historical and challenging.
Black ICE completely overhauls most national focus trees, changes game mechanics, adds in tons of events, technologies, units and much more.
While playing ahistorical will work, Black ICE mainly aims at improving the plausible historical experience.

Current BICE version: v7.0.1 - Checksum: dc5d
Supported HOI4 version: 1.12.11

Supported game language: English ONLY (other languages will produce errors!)
Highly Recommended: Get the Black ICE GFX Add-on here, which adds images to all events.
Make sure to ONLY use Black ICE + Black ICE Gfx, as any other loaded mod most likely will cause issues. Even purely cosmetic mods have been known to cause problems.

- New and improved national focus trees for all majors and most minor nations
- Hundreds of new techs to research, including country-specific armor, aircraft, and ships
- Completely revamped naval system. Customize your ship classes or rely on premade historical designs
- Air War with realistic losses and improved gameplay
- Dozens of new battalion and support unit types
- Extended laws and politics that allow you to fine-tune your strategy
- Immensely detailed, all-new production system, which provides a much more detailed approach to unit equipment
- Events and decisions to completely immerse you in the game and the history it follows
- Improved AI across the board to provide for a more unique challenge

We are proud of our amazing community! Your feedback, praise and constructive criticism drives the project forward, and we are very thankful for it!

Of course a project of such scope does not come without bugs, and we are truly thankful for any messages that bring them to our attention, either here or in the Discord.
Please keep in mind that this is a project we are doing in our free time, so keep it civil. Nobody is forcing you to play the mod. (Although we think you should definitely be playing it!).

Alas, a lot of issues and bugs are out of our hands, as they are a result of un-moddable assets from Paradox.

Go here for the official Paradox troubleshooting in case your game doesn't load, or if it crashes.[support.paradoxplaza.com]

Black ICE has and is being worked on by a lot of dedicated people, and many countless hours have gone into it.

Is there any benefit to purchasing the minor expansion packs if I only play BICE and not vanilla? Will BICE modify Turkey if I purchase Bosporus?

One sincere request: the BI division icon looks so big that almost covers an entire province in normal view. shall we offer a option that able to use the vanilla icon style? Thank you.

Not loading: v7.0.1 is not loading, even when I unsubscribe and resubscribe. When I play all I get is the vanilla version.

Yes, the dogs are gone, but save states lose national policies, can no longer use them, so start again at 0, as so often...... Faith Paradox loves its mod scene

There's a mechanic in the game where the division must manually move to the front line because if there isn't enough supplies; The AI will not move them there.
Check to see if they have that yellow mark mentioned earlier.
check to see if they have the red mark. That means they aren't assigned an order, only to the army.
IF it isn't those two, I wouldn't know.
Hope this helps!

@JackRed, keep the savefile and send it in the discord

No, and that's the problem. It's not a supply problem, because I can manually order the divisions to move. For example, if I plan to attack Denmark and create a front line on the border, then it may happen that only some of the divisions move there and the others do not. And thanks for the quick reply.

Could be insufficient supply available at the front, do your divisions have a yellow ! mark next to them?
